A member asked:

Lengthy cycles my entire life. lmp 4/27 and edd 2/17. is that why edd is 16d away from lmp edd? dr refuses to use lmp dating

A doctor has provided 1 answer

Yes: If your normal cycle is longer than 28 days conception probably occurred later and an early ultrasound is more reliable for dating the pregnancy. Your doctor is trying to be safe and not deliver a premature baby. This is important for you and the baby. Best wishes to you both.
